The Arizona Diamondbacks recalled RHP Matt Koch from Triple-A Reno. Following yesterday's game, the D-backs optioned RHP Braden Shipley to Reno.
Koch, 26, is making his second stint with the D-backs in 2017, as he was also with the team from July 20-22 but did not make an appearance. In 8 starts for the Aces this season, he is 1-2 with a 10.06 ERA (38 ER in 34.0 IP). He registered a quality start in his last outing on Aug. 15 vs. Sacramento (3 ER in 6.0 IP), and has issued 2 or fewer walks in 7 of his 8 starts with the Aces.
Koch made his Major League debut with Arizona in 2016, going 1-1 with a 2.00 ERA (4 ER in 18.0 IP) in 7 appearances (2 starts).
Shipley, 25, is 0-1 with a 6.35 ERA (12 ER in 17.0 IP) in 5 games (2 starts) with Arizona in 2017. He threw 5.2 innings yesterday vs. Minnesota Twins at Target Field, tied for the fourth-longest relief outing in club history.
